Use of pitch-dolomite refractories in steelmaking ladles Chumarin, B. A. et al. Metalhug., 1997, (7) 13-16. (In Russian) Using pitch binder, lime-periclase refractories and the technology for lining ladles with the refractories were developed and implemented. The starting materials used were dolomite and coke pitch. A furnace for heat treatment of linings was developed and put into operation. The composition of the refractories fabricated was CaO 55.5-58.0%, MgO 35.0-37.0%, SiOa 2.5-3.0% and RsOs 3.0-4.0%, they had a density of 2.91-2.93 g/cm3 and a tensile strength of 40-60 MPa.
